4 Claims.

This invention relates to a thread guide for textile machines and asupport therefor.

The invention aims to provide a thread guide and a wire support for thesame so arranged and constructed that the "guide may be easily andquickly removed from or inserted in the support and in which the partsmay be assembled and held in position without the use of wax, shellac,or the like. More specifically, the invention contemplates a threadguide having a base portion and an eye or hook to receive the thread,the base portion on opposite sides having grooves in which the wire ofthe support is adapted to be yieldably and removably received so thatthe guide will be firmly held on the wire support and at the same timebe readily removable therefrom to permit renewal of the guide. I

The invention is illustrated in two forms in the accompanying drawing,constituting a part hereof, and in which:

Figure 1 is a side view of one form of guide and support therefor; I

Figure 2 is a vertical section substantially on the broken line 2-2 ofFigure 1;

Figure 3 is a perspective view of the guide and support separated fromeach other;

Figure 4 is a side view similar to Figure 1 showing a slightly differentform of device;

Figure 5 is an elevation of the arrangement shown in Figure 4, as seenfrom the left in the latter figure; and

Figure 6 is a plan view, partly in section, of the guide shown in Figure4.

Referring to Figures 1, 2, and 3, the guide I0 is provided with a threadreceiving eye IIIA and a base portion IOB which is adapted to be engagedby the wire support II fastened to a part I2 of the textile machine. Onopposite sides thereof the base portion IIlB of the guide is providedwith vertical parallel grooves IUC. These grooves constitute means bywhich the guide is adapted to engage with the wire support II,

The wire support II is made of resilient metal and is shaped or bent asillustrated particularly in Figure 3 to provide a yieldable holder orseat for the guide Ill. To form such holder the wire is bent to providevertical substantially parallel portions or fingers IIA which are sospaced and arranged as to engage in the vertical grooves IDC of theguide when the guide is forced upwardly or downwardly between saidfingers. Rearwardly of the fingers or portions I IA the wire is bentrearwardly and downwardly to form spaced portions IIB which are spacedfrom each other and also from the portions HA.

tions II B are preferably arranged to engage the rear end of the baseIUB of the guide to act as a stop and assist in firmly securing theguide Ill in the holder. Below the portions IIA the wire support I I ispreferably bent rearwardly and then downwardly and then forwardly asillustrated at IIC so that the wire support will serve to hold the guideIt in proper position relative to the part 12 of the machine to which itis attached. The lower end of the wire support II is preferably formedwith an open eye I ID which can be readily engaged under the head of aset screw HE and fastened in position without the necessity of entirelyremoving the screw from its socket.

To assemble the parts of the device, the guide I0 is forced downwardlyor upwardly between the portions or fingers IIA of the holder with saidportions IIA engaging in the grooves I00 on opposite sides of the guide.The rear end of the guide preferably engages the portions IIB of theholder which assist in holding the guide against rearward movement inthe holder. The guide is thus maintained firmly in position on thesupport and at the same time it is yieldably held so that removal orreplacement of the guide may be accomplished without difiiculty.

In the arrangement shown in Figures 4, 5, and 6; the lower portion ofthe wire support I I is the same as that previously described. In thisarrangement, however, the base portion IllB of the guide is providedadjacent its rear end with a shallow groove IIlD which preferablyextends entirely around such base portion and is preferably shaped inthe form of a screw thread. The upper end of the wire support in thisconstruction is formed into a small coil of two or three turns, asindicated at HF, and this coil is of such size as to receive therein andfirmly hold the rear end of the guide Ill with one or more turns of thecoil resting in the'groove IUD of the guide. At the rear of the coil IIFthe wire is bent so as to project laterally across the coil as indicatedat IIG, which forms a stop portion to limit the insertion of the guide Ill in the coil IIG. By

forcing or rotating the end of. the guide I!) into the coil and againstthe stop portion IIG the turns of the coil are slightly expanded and dueto the resilience of the metal, they contract into the groove IUD of.the guide and thus firmly but releasably hold the guide in position onthe support II.

In each form of the device it will be noted that the grooves on theguide are arranged adjacent the rear end of the guide and extend in adirection transverse oi the longitudinal axis of the uide.

Modifications of the structure as described may be made within the scopeof the invention.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. In a thread guide device, in combination, a guide having a baseportion and a thread receiving eye, said base portion having grooves onopposite sides of the surface thereof adjacent its rear end, andextending transversely of the lon gitudinal axis of the guide, asupporting wire for said guide formed of resilient material and havingone end thereof shaped to form a holder for said guide, said holderhaving portions yield ably engaging said grooves on opposite sides ofsaid guide and a portion arranged to engage the rear end of the guide.

2. In a thread guide device, in combination, a guide having a baseportion and a thread receiving eye, said base portion having a groove oneach side thereof, said grooves being arranged parallel to each otherand extending transversely of the longitudinal axis of the guide, a.supporting wire for said guide formed of resilient material and havingone end thereof shaped to form a holder for said guide, said holderhaving two substantially parallel spaced yieldable portions adapted toengage in said grooves of the guide and also having one or more portionsspaced rearwardly from said first named portions and arranged to engagethe rear end of said base portion of the guide.

3. In a guide device, in combination, a thread guide having a groove oneach side thereof arranged substantially parallel to each other andextending transversely of the longitudinal axis of the guide, a holderfor said guide formed of resilient Wire bent to form two spaced fingersengaging in said grooves of the guide and further bent to form one ormore portions which engage the rear end of the guide positioned betweensaid fingers.

4. A holder for a thread guide of the kind having an eye and a baseportion provided with a transverse groove on each side thereof, saidholder being formed of resilient wire and com-o prising two parts, onepart forming a resilient supporting arm and the other part forming aguide engaging portion, said guide engaging portion including two spacedparallel fingers arranged substantially parallel to said supporting armand adapted to engage the grooves on opposite sides of the guide base,and also including two spaced stop fingers, also arranged substantiallyparallel to said supporting arm and adapted to engage the end of thebase, said last named fingers. being spaced laterally from each otherand also spaced rearwardly from said first named fingers.
